Submit RMA to Windmill Computing

Please note:

  • All units returned to Windmill Computing Limited (WCL) for any reason (e.g. warranty repair, refund) must have an authorised RMA number. An RMA number on the outside of the package will speed the process.
  • Merchandise received at WCL without an associated RMA number will be rejected, quarantined and held awaiting return to the sender at their expense.
  • To obtain an RMA number from WCL, you must complete the electronic RMA form below.
  • RMAs will only be issued to customers who bought their unit directly from WCL. Do not send items until we have accepted your RMA request.
  • After you receive an RMA acceptance email including RMA number, please send your package to:
    Windmill Computing Limited
    Broadoak Lodge
    Horsham Road

  • RMA numbers are valid for 14 days from date of issuance.
  • We strongly recommend that you insure and track any package sent to us; we cannot be responsible for merchandise that is damaged or lost in transit.
